pg_dump -C test > ~/Downloads/test.sql && dropdb test && psql < ~/Downloads/test.sql

The following error will be thrown:

ERROR:  function st_bandmetadata(public.raster, integer[]) does not exist
LINE 1:  SELECT array_agg(pixeltype)::text[] FROM st_bandmetadata($1...
                                                  ^
HINT:  No function matches the given name and argument types. You might need to add explicit type casts.
QUERY:   SELECT array_agg(pixeltype)::text[] FROM st_bandmetadata($1, ARRAY[]::int[]); 
CONTEXT:  SQL function "_raster_constraint_pixel_types" during inlining

Can be fixed by changing SET search_path = rasters, pg_catalog; to SET search_path = public, rasters, pg_catalog; in the dump file
